Industrial coatings is very important by enhancing part performance, 耐久性, 美学, 環境要因に対する抵抗. Whether you’re producing precision CNC-machined parts, 構造コンポーネント, or consumer products, selecting the right coating can dramatically affect the functionality and lifespan of your product.
この包括的なガイドで, we’ll explore what industrial coatings are, the most common types used across industries, their properties and benefits, and how to choose the ideal coating for your application.
What Are Industrial Coatings?
Industrial coatings are engineered surface treatments applied to parts or assemblies to provide functional or protective advantages, often as the final step in the manufacturing process. These coatings can:
Improve corrosion and wear resistance
Protect against UV exposure and chemicals
Enhance mechanical strength and thermal stability
Improve visual appeal (色, 光沢, テクスチャ)
Improve electrical conductivity or insulation
で使用されます 自動車, 航空宇宙, 海洋, エレクトロニクス, 工事, そして 産業機械, coatings help meet specific performance, 安全性, and regulatory requirements.
Types of Industrial Coatings
Epoxy Coating – Strong and Long-Lasting
それは何ですか:
Epoxy is made by mixing two liquids—a resin and a hardener. Once they react, they form a thick, tough layer that sticks tightly to the surface.
なぜそれが素晴らしいのか:
非常に耐久性があります
Resists moisture, 化学薬品, and scratches
Works well on many materials
それをどこで使用するか:
Pipelines, garage floors, 機械部品, エレクトロニクス
Simple steps to apply:
Clean the surface (no oil, ほこり, または錆び)
Mix the resin and hardener (follow exact ratios)
Apply it using a brush, roller, or spray
Let it cure (this can take several hours)
Watch out for:
Doesn’t like UV rays (can turn yellow)
Strong fumes—use in a well-ventilated area
Polyurethane Coating – Flexible and UV-Resistant
それは何ですか:
Polyurethane is a coating that stays flexible after curing. It can stretch with the material, so it won’t crack easily.
なぜそれが素晴らしいのか:
Handles sun and outdoor weather
Stretches without breaking
Chemical and abrasion resistant
それをどこで使用するか:
自動車部品, airplane interiors, concrete floors, 海洋部品
Simple steps to apply:
Clean and dry the part
Apply a primer if needed
Mix the polyurethane components
Brush, roll, or spray it on
Allow to cure properly
Watch out for:
Can yellow over time
Not ideal for parts that take hard impacts
Polysiloxane Coating – Tough for the Outdoors
それは何ですか:
Polysiloxane is a high-performance coating that works great in tough outdoor environments. It handles heat, UV rays, and chemicals better than most.
なぜそれが素晴らしいのか:
Super resistant to sunlight and rain
Lasts a long time without fading
Stands up to chemicals and heat
それをどこで使用するか:
橋, wind turbines, chemical tanks, offshore equipment
Simple steps to apply:
Clean the surface thoroughly
Mix base and hardener
Spray or brush it on
Let it cure (some types dry fast, others take longer)
Watch out for:
より高価です
Can become brittle if overexposed
Zinc-Rich Coating – Rust Blocker
それは何ですか:
Zinc-rich coatings work like armor. The zinc corrodes first, protecting the metal underneath—this is called “sacrificial protection.”
なぜそれが素晴らしいのか:
Excellent rust protection
費用対効果が高い
Easy to apply
それをどこで使用するか:
Steel beams, パイプライン, 塔, car frames
Simple steps to apply:
Clean the metal (sandblasting is best)
Apply the zinc coating using spray or dip methods
Let it dry completely
Add a topcoat if needed
Watch out for:
Not suitable for high heat areas
Can look dull over time
Ceramic Coating – Heat and Scratch Proof
それは何ですか:
Ceramic coatings are ultra-tough layers that resist heat, 着る, 化学物質と. They’re used when parts need to survive extreme conditions.
なぜそれが素晴らしいのか:
Withstands very high temperatures
Resists scratches and rust
Chemical resistant
それをどこで使用するか:
エンジン部品, タービン, エレクトロニクス, medical tools
Simple steps to apply:
Clean the part carefully
Use thermal spray, dip, or brush method
Let the coating cool or cure (プロセスに応じて)
Watch out for:
Can be brittle
Requires special tools to apply
More expensive than others
Metallic Coating – Strong and Shiny
それは何ですか:
This coating uses metals like nickel, クロム, or aluminum to add a shiny, protective surface. It can make your parts tougher and more attractive.
なぜそれが素晴らしいのか:
耐食性
Looks good (decorative finish)
Improves conductivity for electronics
それをどこで使用するか:
Electronic parts, 医療用インプラント, 装飾ハードウェア
Simple steps to apply:
Clean the surface
Choose a method (electroplating or thermal spray)
Apply the metallic layer
Buff or polish if needed
Watch out for:
Can require frequent upkeep
Doesn’t stick to all materials
What to Consider When Choosing a Coating?
What Material Are You Coating?
Coatings stick better to certain materials.
Epoxy works great on metal, プラスチック, とコンクリート.
亜鉛 is mainly for steel and iron.
Some coatings don’t do well with rubber or silicone.
✅ Tip: Always check if your part’s material is a good match for the coating.
Where Will the Part Be Used?
Think about the environment:
Will it be outside in the sun or rain?
Near saltwater or chemicals?
Facing extreme heat or cold?
☀️ If it’s going outdoors, polysiloxane または polyurethane are better picks than エポキシ.
How Will You Apply the Coating?
Some coatings are easy to apply with a brush or roller, others need fancy spray tools or special gear.
自分自身に問いかけてください:
Do you need something quick and simple?
Do you have the tools or need a pro?
🧰 If time or tools are limited, go for 亜鉛 または polyurethane.
What Will the Part Need to Handle?
さび? 行ってください 亜鉛 または エポキシ
熱? Try セラミック
柔軟性? ポリウレタン
UV抵抗? Polysiloxane
🛠 Make a quick checklist of what your part needs to deal with—then match it to the coating type.
What’s Your Budget?
Some coatings cost more than others, and some take longer to apply.
💰 亜鉛 is budget-friendly. セラミック そして polysiloxane are more expensive but last longer.
Any Industry Rules to Follow?
Are you making parts for airplanes, medical tools, or food equipment? If yes, you’ll need coatings that follow specific safety or quality rules.
📋 Look for coatings with certifications like RoHS, SGS, または FDA 承認された.
